To aZZ whom, it may concern;

Be it known that LWILLIA E. Sormnmnn,

' a citizen. of the United States, residing at Washington, in the District of Oolu mbia, have invented certain new and useful Improvements in Rotary Hydrocarbon-Engines, of which the following is a specification.

of the valve-operating parts; Fig. i, asection on the line 4 1, Fig. 1; Fig. 5, an elevation showing two engines arranged to secure reversing means. a

- In the preferred form of construction shown the piston has a plurality of explosion-chambers, the casing A is'cylindrical, with hollow walls forming a water-jacket 2, and the piston has a peripheral circular rib 4: at the edge of a disk 3, with a central hub mounted fixedly on the driving-shaft 5, which extends through bring the chamber 6 opposite the inlet-port 7.

hearings in the cylinder." In the piston, as shown, there is a plurality of explosion-chambers 6, although but a single chamber may be used, the said chambers being tangential and each closed at the inner end and opening at, the periphery of the piston, so as to be brought successively opposite an inlet-port7 andthen opposite one or more outlet-ports 8 in the easingA, and between these two ports is arranged or operated. igniting means whereby the charge introduced into the-chamber through the inlet-portds exploded and thereafter escapes through the outlet port or ports on the further revolution of the piston. ;As the chamber is tangential, the explosion of the charge therein acting against the inner end of the chamber and against the opposing face of the interior of the casing tends to force the piston around in the direction of its arrow, and to afford a better abutment for this'a etion I form a recess w in the inner face of the casing with faces so stepped or arranged as to afford abutments or pressure-faces against which the gases may act as the piston rotates.

As' shown, the "exhaust-ports are-.radial and arranged so as to permit the complete escape of the gases after they have sufiiciently expanded' and before the piston hasrotated to Specification of Letters Patent. Application filed October 12, 1903- Serial No. 176,720.

Any suitable means may be employed for forming an explosive mixture, and the same may be introduced into the chamber by any of the usual means for combining and inject: ing a hydrocarbon and air or any other character of explosive charge. As shown, a supplypipe 10 communicates with a chamber 9, formed in the casing A, and this chamber communicates with the inlet-port 7 through a port 12, controlled by a valve 13. This permits the chamber 9 to receive a proper volume'of mixture under high pressure, which can flow suddenly into the chamber upon opening the valve 13. As shown, the valve 13 is upon a stem 14, which is forced inward on rocking a lever 15, operated in any suitable manner from the shaft 5as, for instance, by cams 16, acting upon a guided rod 17, connected to the lever 15, a spring 18 acting to reverse the rocking of the lever and close the valve. i

The igniting means may be carried either by the piston or casing, the latter arrangement being shown and consistingof an electrical igniter C, extending into the chamber 00 and having electrodes carried out .of contact by means of a cam 20 upon a rock-shaft 21, operated by a cams 22, acting upon a guided rod 23, bearing upon a lug on the shaft. 21, and by rocking the latter depressing one of the electrodes to carry it out of contact with the other suddenly, aspring 24 serving to lift the electrode into contact after the explosion.

It will be evident that buta single igniter is required for any number of chambers, it

only being necessary to provide a number of hers.

In order to prevent the escape of gases, the annular head'of the piston 1s recessed to recams 22 corresponding to the number of chamceive annular packings 25, as shown.

In order to-reduce friction, there may be antifriction-balls 27 between the piston and the casing, so arranged as to take the direct bearing of the piston from the casing.

' In some cases it is desirable to allow the spent gases to be forced-out of the rear of the chamber as a new charge is introduced at the front, and to permit this the chamber may have a rear port 40, which when the chamber is in position to receive anew charge may communicate with the port/11 1n the casing,

' this latter port being of-such a length that the port 40 will be closed before the new charge has. passed entirely to the end of the chamber.

The engine as thus described is capable of acting only in one direction. in order to reverse,ll make use of a second engine A, Fig. 5,

of the same character as the first, except that the piston secured to the same shaft 5 has the chamber or chambers 6 open in the opposite direction. The second engine has an inlet-pipe 30, and each inlet-pipe 10 30 has a valve 31, and the stems of the two valves are connected by a link 32 in such manner that when one valve is open the other will be closed. It is therefore only necessary to shift the link 32, which may be done by a hand-lever 33, in order to throw the supply from one engine to the other, when the exploding charges will act with a reverse effect. it will be seen that the piston of the engine which is notoperating constitutes practically a iiy-wheel for the shaft 5 and for the engine which is operated.

In order to start the engine in the first place and bring the chamber 6 into proper position to receive the charge and then into position to cause the charge to be exploded, some means should be provided for readily turning 5 the shaft 5as, for instance, a ratchet 34 on the shaft engaged by a pawl 35, carried by a lever 36, which swings upon a shaft, or any other suitable means may be employed.

When it is desired to spray the oil into the cylinder, compressed air from the pipe 10 may pass to the channel communicating with the port 7, and oil may be admitted to said channel from a pipe 50, communicating with a port 51. This port is controlled by a valve 52., moved from the cams 22 through a rod 53 and lever 44, a spring 55 tending to shift the parts to close the valve.
